### ⭐⭐⭐⭐⭐ Perfect for my needs, some questionable reviews
*by R***T on March 30, 2025*

There are some questionable reviews on this monitor. I’ve been using this monitor since early February. The only downside is even though it’s listed at dp 2.1 but it isn’t the full speed, requiring you to run it with DSC, which honestly hasn’t been an issue for me so far. People are saying the brightness is too low and I disagree completely. I’m willing to bet they didn’t know about the peak brightness increase in the settings. This panel gets extremely bright and rivals the brightness of my lg c1 OLED at high peak brightness in hdr. Also someone mentioned a lack of panel care settings and I also disagree, as there are 4 different pixel shifting modes to choose from, panel cleaning when in sleep, and dimming when displaying static content for long periods of time. Someone also mentioned not being able to tell if the monitor was asleep due to no front light, but there is an led ambient light on the back is you choose to enable it that serves the exact purpose they’re complaining about. If you can catch this monitor for $100+ off, it’s an insanely good panel. Impeccable response times, 480hz, bright hdr, amazing black levels, great build quality and stand, there’s not much more I could ask for in a display. I’ve been enjoying games old and new on this panel at extremely high frame rates and I can never go back. 480hz feels like looking through a window, the motion clarity is something you have to see in person
